DEVICE FOR FILLING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 768,837, dated August30, 1904:.

Application filed February ll, 1904. Serial No. 193,036. (No model.)

To @ZZ whom it may concern:

Be it known that we, RALPH G/VRIGHT and KIRK K. IVRIGHT, residing atBuffalo, in the countyof Erie and State of New York, have inventedcertain new and useful Improvements in Devices for Filling Bottles,ofwhich the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make anduse the same.

Our invention relates to an apparatus for filling milk-bottles and otherreceptacles, and especially to the valves for such an apparatus.

The valve herein shown and described is an improvement on the valvedescribed in our pending application, Serial No. 159,251, filed May 29,1908, for an apparatus for filling bottles.

One of the objects of the present invention is to produce a valve whichcan be easily taken apart for cleaning' and will meet all sanitaryrequirements.

Another object is to produce a valve which can be cheaply constructedand easily and accurately operated.

Other objects will appear from the hereinafter description.v

vWe will now describe our invention indetail in connection with theaccompanying' drawings, which clearly represent our 1nven` tion andwhich form a part of this specification.

Inthe accompanying drawings,Figure 1 is a vertical sectional view of oneof our valves in its normal or closed position and connected to thebottom of atank to contain liquid with which bottles or otherreceptacles are to be filled. Fig. 2 shows the valve in side elevationdisconnected from the tank. Fig. 3 is a vertical sectional View of amodified construction of the valve shown in its closed position andconnected to the bottom of a tank. Fig'. 4: is avertical sectional viewof said modified construction, showing the valve raised or in its openposition. Fig. 5 is a perspective view of a detail.

The Isame parts in the several views are indicated by the same referencecharacters.

On the drawings the part marked 1 represents thc tank.

2 is an internal ly-screw-threaded bushing se- V cured in an opening inthe bottom of the tank, by which the valve 3 is secured to the tank.

4 is a hollow plug screw-threaded to iit in the bushing 2. This plug isprovided on its upper end with a valve-seat 5. A flange 6,

which is formed integral with the plug, rests against the under side ofthe tank. 7 is a downwardly-projecting collar, also formed on this plug.

8 is the opening in the plug, through whichy The lower end of this tubeis provided With a screw-thread 13, which connects with theinternally-serew-threaded portion 14 of another tube 15. These two tubeswhen connected together form a continuous channel, through which theliquid passes from the tank into the bottle when the puppet-valve 12 israised off its seat 5. The tube 15 is enlarged at and above itsscrew-threaded portion 14:, so that when the tubes 9 and 15 are securedtogether a channel or passage-way 16 is left between the outer surfaceof the said tube 9 and the inner surface of the said tube 15.

17 represents openings in the tube 15 just above the screw-threads 14 orat the bottom of the channel 16, these openings and channel being thepassage-way for the escape of air, foam, and overflow milk when a bottleis being filled. The tubel 15 is provided with a iiange 18 above theopening 17 and against which the washer or stopper 19 is fitted.

20 is a sleeve which surrounds and snugly lits over the upper end of thetube 15. The upper end of this sleeve tits around'the collar 7 of theplug 4, with its edge resting against the flange 6 of said plug. Thissleeve is provided with a flange 21' near its upper end, against whichthe upper end of a coil-spring 22, which surrounds the sleeve and thetube 15, rests, the lower end of this spring resting against the flange18. This sleeve is kept in IOO its normal position against the flange 6by the coil-spring 22.

23 is an overflow-spout formed on the sleeve at or above the flange 21.This spout communicates with the channel 16 between the tubes 9 and 15.The upper end of the tube 15 telescoping with the sleeve 20, the ends ofthe coil-spring 22 resting against the flange 18 and the tube 15 and onthe flange 21 on the sleeve 20, the spring tends to force the tube outof the sleeve and keeps the upper end of said sleeve seated in positionaround the collar 7 and against the flange 6 of the plug 4. and keepsthe'valve 12 on its seat 5 on said plug, as is clearly seen from thedrawings. As many of these valves as desired may be connected to thebottom of the tank, as illustrated in my application above referred to.

In operation the bottle to be filled is placed under the lower end ofthe valve-tube 15. The bottle is then raised so that the tube 15projects into the bottle, with the mouth of the bottle resting againstthe washer 19, by which the mouth of the bottle is closed. As the bottleis further raised it raises the tube 15 against the action of the spring22 and telescopes it in the sleeve 20, and as the tubes 9 and 15 areconnected together the puppetvalve 12, carried by the tube 9, is raisedoff its seat 5, as shown in Fig. 1. and the liquid in the tanksuch asmilk, for exampledflows through the opening 10 at the upper end of thetube 9 down through this tube and through the tube 15 into the bottle.As the mouth of the bottle is closed by the stopper 19 foam, air, andoverflow milk pass out of the bottle through the openings 17 and throughthe channel 16, the air escaping at the spout 223 and the milk and foampassing over or through the spout into a receptacle, where it iscollected. l/Vhen the bottle is filled, it is lowered, whereupon thespring 22 forces the tubes 9 and 15 to their normal position, and thepuppet-valve is seated, and the supply of milk to the bottle is cutoil'.

In the modification shown in Figs. 3 and 11 we have formed theoverflow-spout 23 on the upper end of the tube 15, and this spout ofcourse moves with the tube, while in the valve shown by Fig. 2 the spoutis-stationary. To permit this, we have provided the collar or sleeve 2Owith a vertical slot 20E, through which the spout projects and in whichit moves vertically. lVith this exception the operation of thismodification is the same as the other construction above described.

In the construction shown in Figs. 1 and 2 the valve 12 is formedintegral with a butterfly-nut 12, this nut and pin 11 being providedwith left-hand scre\v.-threads, so that the valve may be removed fromthe tube 9 without liability of' the tubes 9 and 15 being separated, orthe tube 15 may be removed from the tube 9 without removing the valve 12from the tube 9, it being understood, of course, that the threads 13 and111 on tubes 9 and 15 are righthanded. In the construction shown by 3the valve 12 is held in place on the lefthanded screw-threaded pin by anordinary nut 12b.. The valve maybe held on in any other well-known way.

To remove the whole valve from the tank without taking out thescrew-threaded plug 4, the tube 15 is held in the hand, and the valve 12is retrieved from the pin 11 by moving the the nuts 12fL or 12, when thetube 9 is pulled out of the plug et, carrying with it the sleeve 20 andspring 22. The tubes 9 and 15 may then be separated by screwing them atthe joints 13 andll. When this is done, all the parts may be thoroughlywashed and cleaned. It is to be noticed that as the openings 17 in thetube 15 are at the bottom of the channel 16 there is no pocket formedwherein milk would settle and collect. Then the tube 9 is removed fromthe tube 15, a brush may be pushed through the openings 17 and the ledgeat the top of the screw-thread 14 thoroughly cleaned.

r1`he tube 15 and the collar or sleeve 18 may be removed withoutremoving the tube 9. rlhis is done by holding the nut 12 or 12" so thatthe tube 9 will not turn. Then by turning or unsere-wing the tube 15from the lower end of the tube 9 the spring 22 and sleeve 2O come offwith the tube 15. These removed parts, as well as the lower end of thetube 9, may be washed and the parts then reassembled.

By our construction it is seen that there are no closed tubes, pockets,or recesses into which milk will collect and become stale and all theparts may be easily and quickly separated and when separated the tubes,sleeve, and spout and all of their parts may be easily, quickly, andthoroughly cleaned.

lVhile in describing the operation of our device we have stated that thebottle to be filled is raised to unseat the puppet-valve 12, it is ofcourse understood that the bottle may be held stationary and the tankhaving our improved valve (or valves) secured to the bottom thereoflowered to the bottle, and when the stopper 19 comes in contact with themouth of the bottle the parts will operate, as heretofore described, toopen the valve 12, permitting the liquid in the tank to flow into andthrough the tubes 9 and 15 into the bottle and the air and overflowliquid to pass out through the openings 17 and the channel 16.

It is to be noticed that the spoutin the first form of our deviceremains stationary and near the bottom of the tank and in themodification, in which the spout moves, it is carried up near the bottomof the tank before the milk overflows. 1n both instances it is seen thatthe overii ow milk is discharged much higher than in the old forms ofvalves. This is quite advantageous, the bottles can be put farther downinthe filling-cases than could be done in the old forms of valves.
